9cd3766f6e - pict_type exported to AVCodecContext 
- Added real_pict_num to AVCodecContext, it represent the number of the
  previous encoded frame, usefull when coding with B frames.
- Warning fix in motion_est.c

9dbcbd92e8 fixed mpeg4 time stuff on encoding 
mpeg4 b-frame enoding support
removed old, out-commented ratecontrol
reuse motion compensation code between encoding & decoding
prefix newly added global functions with ff_ to reduce namespace polution
b-frame ME (unfinished, but working)
added some comments to mpegvideo.h
do MC on encoding only once if possible
bugs? ;)

e03c341ef3 - More work on preliminary bit rate control, just to be able to get an 
average variance for picture's MBs so we can adjust qscale on the MB layer.

37fbfd0a91 - Now the ME is done for the entire picture when enconding, the 
DCT/Quantization is done after we have calculated all the MV of the picture.
- This is the preamble for a better bit rate control.
